Grub not installing


Hi All,

Long story and I hope the history will help.
I was running Ubuntu 8.04 and Windows 2000 on the same HDD. I also have a separate partition for misc linux files (pictures mainly).

Using GParted, I moved and shrunk /dev/sda3 and moved and grew /dev/sda2 (windows). /dev/sda1 is my root. /dev/sda4 is my swap.

I then went an install windows xp over win2K. Of course windows would boot OK. I d/l Ubuntu 9.04 Live CD to install grub. I followed the directions found on the Ubuntu forum and other sources on the Web.

Whenever I though I had install grub, I would reboot, get the splashscreen for my Compaq presario R3000 and be left with a dim flashing cursor, then a regular bright cursor. Grub never loads.

So, I go back to the live CD and try to install again using alternate methods. When I check the /boot/grub/menu.lst file, it is never at the current date.

Finally, I came across the instructions here :https://help.ubuntu.com/community/Re...tallingWindows. Under the title: Overwriting the Windows bootloader. I would mount /mnt/root and /mnt/root/boot. I would check my files to make sure I mounted the correct directory. What I found interesting was to view the contents of /mnt/root/boot. I would have to browsed (in the terminal) to /mnt/root/boot/boot. ???

When I run the grub-install command, it does follow /root/boot/boot.

So, why do I have boot twice. If I open Nautilus, I only have /boot/grub (they way it should be right). If this is just something weird that happens when mounting from a live CD, how do I tell grub-install to look in /root/boot/boot????


Thank you all.


Additional info:

Below you can see the steps that I've taken. Very standard isn't it.
Well, when I browse to /boot/grub/menu.lst the file was still not created today? and grub will still not start at boot time???


ubuntu@ubuntu:~$ sudo grub

Done.

Please let me know if you need further information.

I would suggest your run the command: sudo fdisk -l, compare the output to that of the geometry (hd0) command run from the Grub prompt. If you moved and resized partitions the numbering may have changed.

Hmmm, both are the same.

I don't think you should mount /mnt/root/boot. That is only if you have a separate boot partition which you do not mention having. In your case the boot directory is on your root partition which you say is /dev/sda1. So according to the directions on that page you should:

Code:
mkdir /mnt/root
mount /dev/sda1 /mnt/root
I left off the '-t ext3' part, because it shouldn't be needed.

Code:
ls /mnt/root/boot
That should show you some files that look like kernel and System map and also a grub directory.

Code:
sudo grub-install --root-directory=/mnt/root /dev/sda
That is the command that is supposed to install grub for you in the MBR. Now, the problem I'm thinking you may have is that you have 8.04 installed and are using 9.04 disk to install grub. There is a newer version of grub in 9.04 I think and I think this may be a problem since your grub menu.lst, etc. was created with the older version and may not be compatible with the version of grub being installed in the MBR. I do not know. You may want to get the live cd for 8.04 to do this job if you still have problems.

Thanks Everyone for your suggestions. The system is back up and booting.

I had to change the boot flag back to the windows partition. Then I booted into recovery mode through the windows CD. At the prompt I typed "fixmbr"
Windows was then able to boot.
I searched on how to install GRUB through windows and followed the directions.
At the GRUB prompt I was able to enter the standard commands or root and setup.
BAM everything works again.

Thanks All
